Consider the sliding-bar and resistor apparatus in Griffiths figure. Suppose a constant ofrce of magnitude f pushes the bar through the region of perpendicular magnetic field of magnetic field of magnitude B. Starting from zero velocity, what's the velocity of the bar as a function of time? What 's the current as a function of time?
